Specifications

Model DK 145 is a double-acting low-friction seal for positioning cylinders and pressure accumulators. It consists of an energized slip ring with an O-ring (DFL 106) and, in addition, an X-ring (DFL 111) for dynamic sealing against pressure peaks. The slip ring has such a low coefficient of friction that it eliminates the problem of stick-slip.
- Profile recommended for the separation of two different fluids.
- Excellent housing stability.
- Part free of Stick-slip effect.
The slip ring can be machined in polyurethane and various PTFE formulations. See materials section.
